From 2e91c3694181dc500faffec16c5aaa0ac5e15449 Mon Sep 17 00:00:00 2001 From: Bart Van Assche Date: Fri, 18 Nov 2016 14:26:47 -0800 Subject: [PATCH] dm: use blk_set_queue_dying() in __dm_destroy() After QUEUE_FLAG_DYING has been set any code that is waiting in get_request() should be woken up. But to get this behaviour blk_set_queue_dying() must be used instead of only setting QUEUE_FLAG_DYING.
